1. 太陽フレア・ CME と宇宙天気 Solar Flares/CMEs and Space Weather 浅井歩 (Ayumi Asai) 1 、 下条圭美 1 、 石井貴子 2 、黒河宏企 2 、柴田一成 2 1: 国立天文台野辺山、 2: 京大理

2. 発生源としての太陽 The Sun as a Source Active phenomena on the solar surface (flares/CMEs) work as sources of the outbreaks. The understandings of the generation mechanisms are important. フレア･ CME 伝播 影響 擾乱

3. 太陽フレア･ CME Solar Flare / CME All of these are physically the same phenomena. They are different from each other on one point that they are observed in different aspects.

4. 磁気リコネクション Magnetic Reconnection well explains observed phenomena phenomenologically succeeded (Carmichael 1964; Sturrock 1966; Hirayama 1974; Kopp-Pneuman 1976) still needs to be checked quantitatively and qualitatively

5. プラズモイド噴出 Plasmoid Ejections The combination of SXR ejections and HXR bursts has been observed (e.g. Ohyama & Shibata 1997) Plasmoids play an important role in the reconnection process

6. プラズモイド噴出 Plasmoid Ejections Multiple plasmoid ejections and correlation with HXR emissions (Takasaki et al. 2005?) ② ⑦ ⑥ ④ ③ ① ①②③④⑥⑦

7. pre-eruption During eruption photosphere Initial amount=N Definition of  プロミネンス噴出 Prominence Eruptions gravity force and magnetic pressure work effectively for prominence ejections (Morimoto & Kurokawa 2003a, b)

8. CMEs Strong correlation between CMEs and prominences/plasmoids Similar relation between CME and SXR emission Zhang et al. (2001)

9. CMEs MHD simulation  direct comparison with observation (Shiota et al. 2005, Chen & Shibata 2001)

10. フレアリボン Flare Ribbons H  flare ribbons The evolution of flare ribbons implies successive reconnection  also implies of the strength of the energy release (e.g. Asai et al. 2004)

11. リコネクションレートと ポインティングフラックス An HXR burst occurred on the slit (05:19 UT).

12. 粒子加速 Particle Acceleration Site? Amount?  Mechanism? Masuda et al. (1994) Aschwanden et al. (1996)

13. まとめ Summary Active phenomena on the solar surface (flares/CMEs) work as sources of the outbreaks. The understandings of the generation mechanisms are important.
